I am new to the world of SOAP and XML for that matter. Some of the jargon and what not has been a little daunting.

I am trying to write a SOAP client. I have been provided with XML Schemas of the two web services as well as WSDL schemas. While there are two services, there seems to be several different methods (?) that I can call (e.g. RetrieveOfficeData, RetrieveListingData, etc.).

I was also provided with the following SOAP Example, but am sadly having trouble discerning what is what within the example:

POST /evernetqueryservice/evernetquery.asmx HTTP/1.1
Host: evernet.nwmls.com
Content-Type: text/xml; charset=utf-8
Content-Length: length
SOAPAction: "http://www.nwmls.com/EverNetServices/RetrieveOfficeData"

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" x
+mlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schema
+s.xmlsoap.org/soap/envelope/">
  <soap:Body>
    <RetrieveOfficeData xmlns="http://www.nwmls.com/EverNetServices">
      <v_strXmlQuery>string</v_strXmlQuery>
    </RetrieveOfficeData>
  </soap:Body>
</soap:Envelope>

I have written the following, small perl code to try to work with this method:

#!/usr/bin/perl

use strict;

use SOAP::Lite;



my $num= shift; $num=~/^\d+$/ or die "USAGE: $0 num/n";

my ($server,$endpoint,$soapaction,$method,$method_urn);
$server='http://evernet.nwmls.com';
$endpoint="$server/evernetqueryservice/evernetquery.asmx";
$soapaction="http://www.nwmls.com/EverNetServices/RetrieveOfficeData";
$method='RetrieveOfficeData';
$method_urn='http://www.nwmls.com/EverNetServices';

my $num2words=SOAP::Lite->new(uri=>$soapaction,
            proxy=>$endpoint);

my $response=$num2words ->
    call(SOAP::Data->name($method)
        ->attr({xmlns=>$method_urn})
        =>#Arguments listed next
        SOAP::Data->name(v_strXmlQuery=>$num));

if ($response->fault){
    printf "A fault (%s) occurred: %s\n",
    $response->faultcode,$response->faultstring;
}
else
{ print "$response->result\n";
}

exit;

When I run this, I get the following error:

A fault (soap:Client) occurred: Server did not recognize the value of
HTTP Header SOAPAction:
http://www.nwmls.com/EverNetServices#RetrieveOfficeData.
[download]

So I am thinking that I am confusing things when I assign the method, urn, enpoint, etc.

Given the example provided, how would I decode the following elements: server, endpoint (proxy), soapaction (uri), method, method_urn?
